IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 101,964, dated July5,1870.

To all whom it may concern:

,Be it known that I, JOHN LANE, of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inthe Manufacture of Plow Standards; and I do hereby declare that thefollowing is a full, clear, and exact drscription thereof, referencebeing bad to the accompanying drawings, making part of thisspecification, and to theletters of reference marked thereon, likeletters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, Iwi.l proceed to describe it.

The nature of my improvement consists in making the plowstandard with aprojecting strengthening-rib on the side of a flat-bar upright, and acrooked coupling bar orlug, which is bolted to the under side of theshare and mold-board, which bar or lug is welded to the upright abovethe mold board, substantially as herein set forth and described.

Figure 1 gives a view of my improved plowstandard, of which A is theupright, which is a fiat bar of iron having a rib on one side, as shown.Fig.2 gives across-section view taken on a line, a: w, in Fig. 1,showing the projecting rib a, which gives additional stiffness to thethin bar of iron.

B in Fig. 1 shows a crooked bar of iron, which I call coupling-bar. Toitare bolted the share and mold-board, and the upper part, which isabove the mold-board and extending to the top of the standard, isbentupright, and is welded to the side of the upright A. This crookedcoupling-bar also acts as a brace, giving strength to the plow, and,being welded to the upright A above the mold-board, gives additionalstiffness and strength to the standard. I-sometimes make thecoupling-bar as a short lug.

Fig. 3 gives a view of the plow standard with a lug, O, and shows how itdiffers from coupling-bar B by being short, and to which the mold boardonly is bolted, while the bar B extends under both mold-boardand share.

Fig. 4 gives a view of the plow-standard at tached to the plow.Isometimes welda brace to the back edge of the standard and bolt the topend of the brace to the under side of the beam, as'shown by K.

I do not confine myself to the useof a ribbed standard, as shown, whenusing my improved coupling-bar B or lug O, as a flat bar or any pthershaped bar may be used in combination with the bar B or lug O as I makethem.

I am aware thatit has been common to weld ashort lug on the front edgeof a plow-standa rd to be bolted to theback of the mold-board;

but I am not aware that thelug was ever bent upright and welded to theside of the standard above the mold board to give additional strengthand stiffness to the upper part of the plow-standard.

Having thus described my invention, I claim-- 1. A plow-standard, whichconsists of aflat bar stiffened and strengthened by a projectingangle-piece or rib, when made in one piece and arranged substantially ashown.

2. The uprightA and bar Bo'r lug O, welded together above themold-board, substantially as shown, and for the purpose set forth.

3. The crooked coupling-bar B, Welded to the upright ot' a plow-standardand bolted to the mold-board and share, substantially as shown.-
